INSTALL
- Move any files you want to keep to PC - or you will lose them !

- Swipe to wipe at bottom of screen
- Back to main start screen
- Wipe > format data
- Type ‘yes’ and press blue checkmark at the bottom-right corner

- DO NOT wipe cache / dalvik / art after flashing as this rom is pre-deodexed
- Reboot System! Enjoy!
- Once first boot is completed you can safely move your files back to Internal Storage
NOTICE:
First boot after an install / update takes a while, wait at least 5 - 10 minutes for it to boot.
Phone will be hot / slow after first boot as dex optimisation of your apps occurs and media catalog is built of your audio / video files.
If the LED stops flashing and goes solid with any color then SuperSU did not correctly trigger the reboot. You can either pull the battery -OR- hold down the power button for 15 seconds till the led / screen goes blank, then let go of the power button. Then after another 4 seconds it will automatically boot and vibrate and everything is 100% normal. It only happens that one time on a new Rom install with SuperSU.
